Declaration
property LoadToWidth: integer;
Description
Specifies the minimum width for the image when loading.
Set
LoadToWidth and
LoadToHeight to the display size for this image and it will be loaded more quickly when:
◼Loading JPEG and
JPEG_Scale=
ioJPEG_AUTOCALC◼Loading JPEG2000 and
J2000_Reduce=-1
◼Loading
PDF files if
AutoScaleImport=True
◼Importing
Meta files if
AutoScaleImport=True
◼Loading
ImageMagick files if
AutoScaleImport=True
Note:
◼Set
LoadToWidth and
LoadToHeight to 0 to reset optimized loading
◼ImageEn will consider the aspect ratio to ensure both
LoadToWidth and
LoadToHeight exceed the minimum specified values (so the final size will generally be larger than the specified values)
Default: 0
// Load a JPEG as fast as possible, ensuring width is >= 150 and height >= 100 (while maintaining the aspect ratio)

ImageEnView1.IO.Params.LoadToHeight := 100;
